RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Milos Malik 2016-12-01 10:47:12 UTC 
Description of problem:
  -E, --extract         Extract customizable commands, for use within a
                        transaction
If the extract option is used in a transaction then the security range is lost.

Version-Release number of selected component (if applicable):
policycoreutils-2.5-8.el7.x86_64
policycoreutils-python-2.5-8.el7.x86_64

How reproducible:
* always

Steps to Reproduce:
# seinfo --nodecon
Nodecon: 0
# semanage node -l
# semanage node -E
# semanage node -a -M 255.255.255.0 -p ipv4 -t node_t -r s0-s0:c0.c1 192.168.0.123
# seinfo --nodecon
Nodecon: 1
   nodecon 192.168.0.123 255.255.255.0 system_u:object_r:node_t:s0 - s0:c0.c1
# semanage node -l
IP Address         Netmask            Protocol Context

192.168.0.123      255.255.255.0      ipv4  system_u:object_r:node_t:s0-s0:c0,c1 
# semanage node -E
node -a -M 255.255.255.0 -p ipv4 -t node_t 192.168.0.123
# 

Expected results:
* the security range is also printed
Comment 1 Milos Malik 2016-12-01 10:51:03 UTC 
The same issue is reproducible with semanage interface:

# seinfo --netifcon

Netifcon: 1
   netifcon xyz system_u:object_r:netif_t:s0 - s0:c0.c1 system_u:object_r:netif_t:s0 - s0:c0.c1
# semanage interface -l
SELinux Interface              Context

xyz                            system_u:object_r:netif_t:s0-s0:c0,c1 
# semanage interface -E
interface -a -t netif_t xyz
#
Comment 2 Milos Malik 2016-12-01 12:57:33 UTC 
My guess is that all semanage sub-commands which support -E, --extract options suffer from this issue:

# semanage fcontext -l -C
# semanage fcontext -a -t tmp_t -r s0:c0.c1 /pokus
# semanage fcontext -l -C
SELinux fcontext                                   type               Context

/pokus                                             all files          system_u:object_r:tmp_t:s0:c0.c1 
# semanage export
boolean -D
login -D
interface -D
user -D
port -D
node -D
fcontext -D
module -D
fcontext -a -f a -t tmp_t '/pokus'
# semanage fcontext -E
fcontext -a -f a -t tmp_t '/pokus'
# 

The export sub-command of semanage does not print the MLS/MCS security range either.
Comment 5 Milos Malik 2017-07-17 07:58:24 UTC 
Because the export option for user and login sub-command prints MLS/MCS security range:

# semanage user -E
user -a -L s0 -r s0 -R 'user_r' user_u
user -a -L s0 -r s0 -R 'xguest_r' xguest_u
# semanage login -E
login -a -s unconfined_u -r 's0-s0:c0.c1023' __default__
login -a -s guest_u -r 's0' guest-user
login -a -s staff_u -r 's0-s0:c0.c1023' staff-user
login -a -s user_u -r 's0' user-user
login -a -s xguest_u -r 's0' xguest
login -a -s xguest_u -r 's0' xguest-user
# 

it would be great if the export option also printed MLS/MCS range in case of other sub-commands. Otherwise the export/import mechanism looses information.

# grep semanage /usr/libexec/selinux/selinux-policy-migrate-local-changes.sh 
        if [ -x /usr/sbin/semanage ]; then
            /usr/sbin/semanage export | /usr/sbin/semanage import
